WINDOW-HOLDER.

Specification of Letters Patent.

Patented Sept. 21, 1915..

Application filed October 8, 1914. Serial No. 865,649.

To all whom it may concern Be it known that I, OSCAR JOHNSON, a citizen of the United States, residing at Starks, in the county of Oneida and State of Wisconsin, have invented certain new and useful Improvements in Window-Holders, of which the following is a specification.

The present invention relates to certain new and useful improvements in window holders, and has for its object to provlde a device of this character which embodies novel features of construction whereby the sash can be quickly and firmly locked at any desired height without injury to the wlndow casing.

A further object of the invention is to provide a sash holder which is comparatively simple and inexpensive 111 1ts construction, which can be easily and quickly manipulated, which is not liable to be broken or to get out of repair, and which can be readily applied to any sash.

\Vith these and other objects in'view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, 111 which Figure 1 is a perspective view of a sash holder constructed in accordance with the invention, showing the same as applied to a window. Fig. 2 is a front elevation of the same with portions broken away and shown in section to more clearly illustrate the invention, the locking lever being shown by full lines in operative position and by dotted lines in inoperative position. Fig. 3 is an enlarged detail view of that end of the operating lever which engages the window casing with portions broken away and shown in section to show the manner of applying the soft rubber nose thereto.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to the drawings, the numeral 1 designates a portion of a window casing and 2 a portion of a window sash which is slidably mounted upon the window casing and has a sash holder constructed in accordance with the invention applied thereto.

In carrying out the invention a bell crank lever 3 is provided and this lever is pivotally mounted as indicated at e upon a suitable base plate 5 which is designed to be secured to the sash 2 at a point adjacent the window casing 1. One arm 3 of the bell crank lever 3 extends downwardly and terminates in a laterally projecting arm 5 which passes through an opening 6 in one end of an inclosing box or housing 7 which is applied to the base plate 5 and receives the lever 3 within the same. This lateral arm 5 has a soft tip 8 of rubber or other suitable ma terial applied thereto, said rubber tip pro viding a nose which is adapted to frictionally engage the window casing 1 to lock the sash against sliding movement. In the present instance, as indicated by Fig. 3, the rubber tip 8 is shown as formed at the base thereof with a tongue 8 which is allowed to expand within an undercut recess formed in the extremity of the arm 5 so as to hold the rubber tip securely in position. The opposite arm 3 of the bell crank lever 3 terminates in a longitudinally disposed spring arm 9 which passes through a slot 10 in the outer end of the box 7 and is normally in a yielding engagement with the teeth or serrations 11 provided at one edge of the slot 10. The extremity of the spring arm 9 projects upon the exterior of the housing 7 and terminates in a finger piece 12 which is pressed downwardly when it is desired to forcibly project the rubber tip or nose 8 into engagement with the window casing to lock the sash in an adjusted position. Owing to the spring action of the member 9, the tension therein when the finger piece 1.2 is pushed downwardly will serve to hold the nose 8 in a firm but yielding engagement with the window casing so that a friction lock will be produced which will hold the window sash against sliding movement. A coil spring 13 is arranged within the housing 7 and has one end thereof connected at 14. to the arm 3 of the bell crank lever, while the opposite end thereof passes loosely through an opening 15 in the end of the housing 7 and has the finger piece 16 applied thereto. The two finger pieces 12 and 16 may be conveniently grasped between the thumb and forefinger when it is desired to throw the sash holder into operative position. When it is desired to release the sash holder, the finger piece 12 is pulled outwardly to disengage the spring arm or extension 9 from the serrations 11, and the finger piece 16 simultaneously pulled upon to increase the tension in the spring 13 and forcibly throw the locking lever into in operative position, as indicated by dotted.

lines on Fig. 2.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent, is V A sash holder including a base plate adapted to be secured to the sash, a housing applied thereto and having an opening at each end thereof, one end thereof being also formed with a slot having one edge thereof serrated, a bell crank lever pivotally mountopenings of the housing and is adapted to engage thewindow. casing to lock the sash against sliding movement, a tension spring havingone end thereof connected to the second mentioned arm of the bell crank lever While the. opposite end thereof passes through the opening in that end of the housing provided With the slot, and a finger piece applied to the said end of the spring and arranged in an opposed relation to. the finger piece at the extremity of the spring extension of the bell crank lever, the tension spring serving to sWin-gthe bell cranklever nto inoperative positionas soon as thei spring extension is" released from engagement With the serratededge the slot.

In testimony whereof I affiX'my signature in presence oftwo itnesses.
